In extrusion-based additive manufacturing, achieving high surface quality typically involves using small layer heights to reduce the size of grooves between layers. However, this approach can be both less effective and time-consuming in big-area addi

In a ternary mixture with Soret effect, the interplay between cross-diffusion, thermodiffusion, and convection can lead to rich and complex dynamics, including spatial patterns and oscillations. We present an experimental...
